Definitions

  • the invention relates to an articulated sliding gate.
  • the invention also relates to a ground sliding device particularly for articulated sliding gates.
  • Such an articulated sliding gate generally comprises a barrier composed of a plurality of sections, each of which in the form of a chassis, or plate, or other similar element, arranged one after the other and articulated so that two side by side sections can rotate one relative to the other around a vertical axis.
  • An articulated sliding gate also comprises sliding wheels and guide means for said wheels, for example a rail and at least two columns, configured to support and guide the barrier according to a predetermined path, and possibly, but not exclusively, motorization means, for example an electric gearmotor associated with a rack-pinion system, for actuating the movement of the barrier between an opening position and a closing position.
  • motorization means for example an electric gearmotor associated with a rack-pinion system, for actuating the movement of the barrier between an opening position and a closing position.
  • Each section has at least one wheel at the bottom.
  • a particular type of articulated gates is known today in which the sliding wheels are connected, for example rotatably with respect to a vertical axis, to a piston element, which piston element is inserted in an upright which, in turn, is part of the section of the barrier.
  • a helical spring configured to push the piston element downwards, and therewith the sliding wheel constrained thereto, is placed to act on said piston element.
  • tubular upright is generally constituted by the lower stretch of an upright of each section of the articulated barrier.
  • Another drawback of said known anti-derailment system is constituted by the fact that it can only be installed on barriers whose sections have at least one tubular upright capable of accommodating in its inside the piston element carrying the wheel, the helical spring and the abutment, the latter being configured to receive the helical spring for resting; this makes it impossible to mount such an anti-derailment system on sections of barriers which do not have tubular elements of suitable dimensions at the vertical sides.
  • said anti-derailment system cannot be installed on gates already in place and without a lower hole at the upright designed to accommodate the abutment for the spring, the helical spring and the piston element, except after the specific execution of said lower hole.
  • the task of the present invention is to develop an articulated sliding gate capable of obviating the aforementioned drawbacks and limitations of the known art.
  • Another task of the invention is to develop a ground sliding device particularly for articulated sliding gates.
  • an object of the invention is to develop an articulated sliding gate that is simple to install and safe with respect to the derailment risk.
  • Another object of the invention is to develop a sliding device capable of ensuring an effective anti-derailment system.
  • a further object of the invention is to develop a compact and easy to install sliding device, even on already existing gates.

  • the rotatable constraint means 80 comprise:
  • the rest and sliding wheel 13, like the wheels 13a and 13b, are therefore pivoting wheels able to rotate with respect to the section 11b, 11c, 11z to which they are associated.
  • FIGs 13, 14, 15 and 16 show two different operating positions of said pivoting wheels, similarly to what has already been described and represented in Figures 7 and 10 for the non-pivoting wheel 12.
  • Such a peculiar position of the pin 43 of the wheel 13 allows achieving an optimal load transmission from an overlying section 11b, 11c to the wheel 13 itself through the rotatable constraint means 80, without a torque developing between the vertical axis X3 of the pin with vertical axis 83 and the axis of horizontal rotation X1 of the wheel 13 which may compromise, over time, the integrity of the components.
  • the distance B1 between the vertical axis X3 and the axis of horizontal rotation X1 can vary between 0 and 10 millimeters.

  • said ground sliding device 90 comprises means for rigidly fixing the bearing body 16 to a lower portion of a section of an articulated barrier 11.
  • said ground sliding device 190 comprises constraint means rotatable around a vertical axis for constraining said bearing body 16 to a lower portion of a section of an articulated barrier 11.

Practically, it has been established that the invention achieves the intended task and objects.
  • an articulated sliding gate has been developed that is easy to install and safe with respect to the derailment risk, thanks to the push system on the wheel-holder element which ensures the continuous automatic adaptation of the rest and sliding wheels to the effective position of the guide.
  • ground sliding device can be fixed in any position under a section of the articulated gate, even away from an upright.

La présente invention concerne une porte coulissante articulée (10) comprenant : - une barrière articulée (11) comprenant au moins deux sections (11a, 11b) articulées l'une à l'autre par un moyen d'articulation à axe vertical (Y) ; - une pluralité de roues d'appui et coulissantes (12, 13) pour la barrière articulée (11), lesdites roues d'appui et coulissantes (12, 13) étant reliées à une section respective (11a, 11b) chacune au moyen d'un élément porte-roue (15) et au moyen d'un moyen de poussée de l'élément porte-roue (15) vers un guide de coulissement (14) ; - un guide de coulissement (14) pour les roues d'appui et coulissantes (12, 13). Le moyen de poussée d'un élément porte-roue (15) comprend : - un corps de palier (16) limité à une partie inférieure d'une section (11a, 11b) ; un moyen d'articulation (17) pour la contrainte rotative de l'élément porte-roue (15) par rapport au corps de palier (16) autour d'un axe de rotation (X2) parallèle à l'axe de rotation (X1) de la roue (12, 13) ; un moyen de poussée élastique (18) conçu pour pousser l'élément porte-roue (15) en rotation autour de l'axe de rotation (X2) de telle sorte que les roues d'appui et coulissantes (12, 13) s'éloignent du corps de palier (16). Le corps de palier (16) est limité à la partie inférieure d'une section (11a, 11b) par un moyen de contrainte rotatif (80) à axe vertical.
